Re it known that L HENRY G. Enreono, a

citizen of the: United States7 residing at Chicago, in the county ofCook and Statev preventing derailment of rolling stock.

My improved Aguard rail is an integral structure as distinguished fromthe struetiiresin common use which are built upfrom stock ia-iie.

referably my v.,vuard rail is constructed of manganese steel, but theinvention. is not necessarily limited thereto and may be vioi'nied ci'an material capable of with stanc'iing ille ocks .to which it issubjected iii practice;

The particular object and nature of the invention will more clearlyappear from the foliowing; description and claims, taken in coiniectionwith the accompanying drawings, in Whiciif Figureis a plan View of myimproved guard rail showing 6i-fragment oi a traffic reil and theunderlying ties assembled therew Fig. 2 is an elevation of my .improvedetrncture rom the inner side.,` Fig. 3 is a similar eloyetion from'theouter side.

"clination and leno'tli advante thereby epaced inwardly from the traiicrz .i a, `suiiicient distance to permit the nee oi' spikes along: theedge of the inner hase flange of the ti'atlic rail, Thiais of especialimportance :is the traido rail opposite e, 'guard rail, es pccialiy uponcurves, is opt to become tilted and loosened unless: securedby spikesalong its inner edge. A further :idyantage resulting from 'the use ofthe sloping web 3 arises from the fact that in interurban raiinmy trackconstruction, the throat orjspaee between the guard rail and trailicrail ia narrower than in standard railway conetrnction. By sloping' theweb 3 as herein described the throat may be .made ae. narrow asnecessary Without bring ing ihe lower part oi' the web too close todinal arms G overlying the iicijacent The arms G extend outwardlyhej/ond the outer onse Harige oi the trailic rail 2' and are providedwith inclined slots 8, tlieinclination and l ot' these slots coing suchthat `ro receive a. trai'iic rail heiding en i oil the positions towhich the tra'ic rail. needs to he adjusted. The ini the slots also areeuiiicicnt to enable the evice to he ii-sed. with tratlic rails havingdiii'erent widths olf base. Near iheir outer edge-fe the arms G are piovided with upwardly projecting luge ha 'ing inclined inner faces i0,which are pret- 'erably, though not necessarily, corrugated.

Wedges il having correspondingly inclined faces-i12, which also arepreferably corrugated, are adapted to lie between the lugs 9 and theedge of the'outer base fiange of the trallic rail. The wedges 11 arevprovided with spike holes or openings i3 shown in the present imi-ancein the 'form of notches in the inner sides of said Wedges. Near theirinner edges the arms t3 are provided with spike holes M "elongatedtransveieely of the track in order 'to receivespikee' ihaiiy one of apiurality ci? positions in order in, various positioni and .nt Widths ofhase ilange. The heee `plate i ie also provided with spike hoiee ed@ ntite edgefandithc hase accommodate r rails having' di plate is preferablyrecessed at 16 over r'the spaces between the ties in orderto lighten thestructure. Similar recesses 17 are also preferably provided at theopposite side of the structure between the arms 6.

In assembling the device, the guard rail structure, which is vformedintegral throughout, is placed in position upon the ties 18 and theresecured by means of spikes. The traflic rail 7 is placed inA theposition illustrated in Fig. 1, upon the arms 6 of the projections 7 andthe wed esv 11 are adjusted between the lugs 9 and t e outer baseflangeof the traffic rail. The inclined faces 10 and 12 upon the-projections 9 and wedges 11 permit the wedges to be adjusted in suchposition as to secure the proper track gage. Inthe event that theinclined faces of the lugs and wedges are corrugated, the' corrugationsmay be so proportioned -that movement of the wedge a distance equal toone corrugation will adjust the rail a predetermined amount-say aneighth of an inch. By the use of the wedges 11 in connection with thelugs 9 the outward thrust upon the traiiic rail is transmitted throughsolid metal to thel uard rail structure without imposing any endinstress upon the spikes, as is the case when tespikes pass through anenlarged opening in the base Aplate without lateral support above theties. The inclination of the slots 8 permits the driving of a spikethrough the opening 13 of the wedge and said slot in'any adjustedposition of the wedge, and the transverse elongation of the spike holes14 along the inner edges of the arms 6 permits the driving of spikes tosecure the in'ner'base flange of the trahie lrail in anyof its adjustedpositions. Preferably the projections 5 are strengthened by transverseribs 20 extending downwardly therefrom and lying between the ties.

The use of the wedgesl 11 in connection with the lugs 9, as abovestated, has the effect of transmitting the outward .thrust .upon thetraiiic rail t0 the guard rail structure through an all-metalconstruction,

Awhereby the outward thrust upon the traiiic rail is resisted by all ofthe spikes holding the guard rail structure to the ties and no bendingstress is imposed upon the spike at the outer edge of the traffic rail.The particular foi-m of the transverse extensions, comprising theprojections 5 and varms 6, is such as to secure a rigid connectionbetween the guard rail andtraic rail, at the saine time providing, ineffect, tie plates for the traffic rail, with the. use of a `minimuinamount of metal.

1While I haveY described a specific form of my invention, it will beunderstood that the principle may be applied withoutadhering to theprecise forni illustrated and described.

It will be noted thatart of the slots 8 and the inner surfaces ong-)partof the lugs 9.

incline in one direction and the remainder in the opposite direction. Bymeans of this arran'geinent the structure etfectually prevents creepingofthe trafficrail longitudinally. Any tendency to creep in eitherdirection has the effect of tightening part of the Wedges 11 and thereby`more firmly clamping the rail.
